针对风电机组复杂多变的工作条件和自身控制要求,文章提出了一种基于Mamdani模糊推理的风电机组控制方法.该方法首先对控制对象进行模糊化处理,然后制定推理规则并确定控制推理方式,最后对推理结果进行精确化模块处理,反馈给控制对象.文章以风电机组偏航系统控制为例,研究了在风速大小、风速变化和风速变化率3种因素下调桨量的模糊控制,试验结果证明了该方法可以满足变工况下风电机组变桨控制要求.%Aimed at the changeable working condition and the control requirement of the wind turbine, a wind turbine control method based on the Mamdani fuzzy inference is proposed. This method deals with the controlled member with the fuzzification process at first. Then the inference rules and the control inference are identified. At last the inference results are precisely turned in order to output to the control member. In the end of this paper, the wind turbine yaw system control problem is taken as the example, the fuzzy control problem under 3 input factors such as speed, speed change and speed change rate is analyzed in detail. The results proved that the control method can satisfy the wind turbine yaw control requirement and can be expanded into the wind turbine control system.
